The English and Maths results of 10 classmate's area unit shown within the table below: ![]() If there is a link it is referred to as correlation. By looking at the diagram you will see whether or not there is a link between variables. Scatter diagrams show the link between 2 variables. The frequency polygons are significantly helpful for scrutinizing completely different sets of information on an identical diagram. You can construct a frequency plane figure by connecting the midpoints of the super of the bars. This frequency diagram shows the heights of 100 people: This chart shows the results of a survey to search out however students travel to school:Ī) What's the most common technique of travel?ī) What fraction of the scholar's travel faculty by car?Ĭ) If half a dozen students travel by car, what percentage of folks took half within the survey?įrequency diagrams and frequency polygons Pie charts must always be labeled, either directly on the chart or by suggesting that of a color-coded key. In a chart, it's necessary to grasp that the angle of every sector represents the fraction, out of 360, allotted thereto information price. ![]() Pie charts use different-sized sectors of a circle to represent information.

To confirm an applicable scale, vary the axes uniformly and provide the acceptable label on the axes. The labeling of the x-axis depends on what's being portrayed by the chart. In the bar chart, the peak of the bar shows the frequency of the result.Īs the height of the bar represents frequency, the y-axis would be called frequency. ![]() The other thing you should consider is that each graph needs SALT, ensure you bear in mind the information:Ī chart is employed to match two or additional values with the least set of results.
